StarCraft II: Wings of Liberty is the long-awaited sequel to the original StarCraft, Blizzard Entertainment’s critically acclaimed sci-fi real-time strategy game. In typical real-time strategy games, players build armies and vie for control of the battlefield. The armies in play can be as small as a single squad of Marines or as large as a full-blown planetary invasion force. As commander, you observe the battlefield from a top-down perspective and issue orders to your units in real time.
